Is the App Available on the App Store?

No. Download the desktop app from the website using the links above and install it manually.

Installation on macOS

  • Double-click the downloaded .DMG file.
  • In the window that appears, drag the app icon to the Applications folder.
  • Launch the application. On the first launch, macOS will inform you that the application was downloaded from the internet and checked for malware — click Open.
  • Allow the application to access devices on the local network — click Allow.
    ⚠️ Without this permission, connection issues may occur. If you accidentally clicked Deny, enable access manually: System Settings > Privacy & Security > Local Network > enable the toggle for the application, then restart it.

Installing Certificates on macOS

CTS
ETS

By default, you do not need to install corporate server certificates. If connecting does not work without them, install them:

  1. Open the macOS Keychain Access app. You can find it through Spotlight search.
  2. Select System.
  3. Drag the certificate file into the Keychain Access app.
  4. Enter the computer administrator's username and password.
  5. Double-click the added certificate, expand the Trust section, and for the When using this certificate option, select Always Trust. Close the window and confirm the change with your password.
  6. The app continues to run in the menu bar. Quit it completely and launch it again.

⚠️ Without the fifth step, connecting to the server won't work: the app doesn't use the certificate if trust isn't enabled for it.

If your organization's server has switched to Ministry of Digital Development National Certification Authority certificates, see the instructions.

Credential Storage on macOS

Authentication data is stored in the keychain. To view keys, open the Keychain Access app on macOS. You can find it through Spotlight search.

For Administrators: Managing Keys Storage

Keyring Password

If the keychain has not been used before and no password has been set for it, you will be prompted to create a password the first time you launch the application. ⚠️ On subsequent launches of the application, the system may require you to enter this password again.

Deleting Keys

If you delete authentication keys from the keychain, the authentication screen will appear after restarting the app. When uninstalling the app normally, the keys are preserved.

Application-Specific Keystore

ETS
Since version 3.42, you can configure a non-system app keystore in the ~/Library/Application Support/app_name folder in an
ETS
build. Contact eXpress support to get more details.

Updating on macOS

The app finds updates on its own and offers to install them (details). Check for updates manually: Settings (avatar button) > Check for updates.

For Administrators: Additional Update Options

Disabling Update Checks

  • Create an AppConfig.json in the /Users/user_name/Library/Application Support/app_name folder and add:
    { "AutoUpdate": false, "Update": false }
    Pre-made file: AppConfig.json. Version 3.54 or above is required.
  • Or, block access to the updates.express.ms resource. If an
    ETS
    app has its own update server configured, the app uses it.

Standard Update

To update the app manually, install the new version in the same way as during a normal installation.

Uninstallation on macOS

Standard Uninstallation

  1. Close the desktop app: select Quit in the Dock.
  2. Open Finder > Applications > find the app and drag it to the Trash > empty the Trash.
For Administrators: Complete App Removal on macOS

Perform this as recommended by support: for example, to delete credential keys saved on the computer.

    ETS
